Question 1

What is the Meaning of Articular Cartilage?

Accepted Answer

Articular cartilage is the smooth, resilient connective tissue covering bone ends within synovial joints. Composed of chondrocytes in an extracellular matrix of collagen and proteoglycans, it provides a low-friction surface for joint movement. It enables flexibility and compression resistance, facilitating efficient, pain-free motion.

Question 2

What is the Context of Articular Cartilage?

Accepted Answer

This crucial biological component operates within the musculoskeletal system, specifically at the interface of articulating bones in diarthrodial joints. It functions as a vital structural element, enabling smooth gliding of bone surfaces and protecting subchondral bone. Its integrity is essential for maintaining joint function and efficient physical activity.

Question 3

What is the Significance of Articular Cartilage?

Accepted Answer

Clinically, articular cartilage integrity directly impacts joint health; its degradation is the hallmark of osteoarthritis, a prevalent chronic condition. Patients experience pain, stiffness, and reduced range of motion as cartilage deteriorates, impacting daily function. Assessing its status is crucial for diagnosis, guiding treatment, and managing symptoms.

Question 4

What is the Mechanism of Articular Cartilage?

Accepted Answer

Articular cartilage exerts its effect through remarkable biomechanical properties: low friction and viscoelasticity. During joint movement, the cartilage surface allows opposing bones to slide with minimal resistance, lubricated by synovial fluid. Under compression, the tissue deforms to absorb and dissipate forces, protecting underlying bone from stress.

Question 5

What is the Application of Articular Cartilage?

Accepted Answer

In clinical practice, managing articular cartilage involves preventive strategies and interventions for damage. Orthopedic specialists use approaches like physical therapy, lifestyle modifications to reduce joint stress, and, for significant damage, surgical procedures. Individuals can support cartilage health through balanced nutrition and low-impact exercise.

Question 6

What is the Metric of Articular Cartilage?

Accepted Answer

Articular cartilage status is assessed through clinical and diagnostic metrics. Radiographic imaging, like X-rays, reveals joint space narrowing. MRI provides detailed visualization of cartilage thickness and integrity. Clinicians also evaluate patient symptoms, joint range of motion, and pain levels, using standardized questionnaires.

Question 7

What is the Risk of Articular Cartilage?

Accepted Answer

Compromised articular cartilage presents significant clinical risks, primarily leading to osteoarthritis progression, chronic joint pain, and functional disability. Trauma, repetitive stress, advanced age, and metabolic imbalances can accelerate breakdown. Without appropriate management, deterioration can become irreversible, potentially necessitating extensive surgical interventions.
